Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
net: cpsw_new: Fix potential unregister of netdev that has not been registered yet<br />
<br />
If an error occurs during register_netdev() for the first MAC in<br />
cpsw_register_ports(), even though cpsw->slaves[0].ndev is set to NULL,<br />
cpsw->slaves[1].ndev would remain unchanged. This could later cause<br />
cpsw_unregister_ports() to attempt unregistering the second MAC.<br />
To address this, add a check for ndev->reg_state before calling<br />
unregister_netdev(). With this change, setting cpsw->slaves[i].ndev<br />
to NULL becomes unnecessary and can be removed accordingly.
